Abstract
Description
Technical Field
[0001] This utility model belongs to the field of nozzle technology, and specifically relates to a fine water mist nozzle. Background Technology
[0002] Fine water mist nozzles are commonly used in agriculture and industry. They achieve uniform spraying and atomization by dispersing liquid into small droplets. The working principle of fine water mist nozzles is based on the fact that liquid is subjected to high pressure inside the nozzle and sprayed through small holes or slits, thus creating an atomization effect. The high-pressure spray principle involves using a high-pressure pump to push the liquid into the nozzle. Under high pressure, the liquid rapidly accelerates, forming a high-speed jet stream, which is then dispersed into small droplets by the impact of air and the shear force of the liquid. The atomization principle involves the nozzle orifice having a micro-aperture or slit, which divides the jet stream into many small streams. These streams collide and mix, forming small droplets suspended in the air. Fine water mist nozzles are suitable for extinguishing fires on flammable solid surfaces, flammable liquids, and some electrical equipment in relatively enclosed spaces. They are mainly used in libraries, archives, high-rise buildings, production workshops, cable tunnels, oil-immersed transformers, boiler rooms, electronic information system computer rooms, generator rooms, and other similar locations.
[0003] Currently, fine water mist nozzles are connected to the water supply pipe via an internal threaded connector. However, due to the thread seal being prone to leakage when not properly tightened or after repeated disassembly and reassembly, a sealing ring is sometimes fitted onto the connector to enhance the seal. However, the simply fitted sealing ring is prone to loosening and falling into the fine water mist nozzle connecting pipe, causing difficulties in removal. Utility Model Content
[0004] The purpose of this invention is to provide a fine water mist nozzle to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fine water mist nozzle, comprising a water mist nozzle connector, wherein a water mist nozzle is fixed at the lower end of the water mist nozzle connector, and a positioning and sealing mechanism is provided inside the water mist nozzle connector, the positioning and sealing mechanism comprising a positioning and reinforcing tube and a sealing gasket, the positioning and reinforcing tube passing through the inside of the water mist nozzle connector, and the sealing gasket being sleeved on the outer surface of the positioning and reinforcing tube. Through the positioning and sealing mechanism, the end face of the connected water supply pipe applies a pressing pressure to the sealing gasket and achieves the function of sealing and preventing leakage. In addition, the positioning and reinforcing tube plays a positioning and guiding role during the installation of the water supply pipe and reduces the possibility of misalignment.
[0006] The lower end of the positioning and reinforcing tube is fixed with a threaded collar. Through the threaded collar and the positioning and reinforcing tube, the sealing gasket can be lifted by removing the positioning and reinforcing tube during the replacement of the sealing gasket, thus achieving the effect of easy disassembly and assembly.
[0007] It should be noted in the solution that the inner wall of the water mist spray pipe connector is provided with an inner spiral pattern, and the side surface of the threaded collar is provided with an outer spiral pattern.
[0008] It is worth noting that the outer helix of the threaded collar matches the inner helix of the water mist spray pipe connector, and a accommodating gap is provided between the positioning and reinforcing tube and the water mist spray pipe connector.
[0009] Furthermore, it should be noted that the sealing gasket has an assembly opening inside, which is compatible with the positioning and reinforcing tube.
[0010] In a preferred embodiment, the sealing gasket is disposed between the water mist spray pipe joint and the positioning and reinforcing pipe, and the positioning and reinforcing pipe has a water inlet inside.
[0011] In a preferred embodiment, the water mist nozzle connector has a water passage cavity groove inside, the water inlet of the positioning and reinforcing pipe is connected to the water passage cavity groove of the water mist nozzle connector, and a fine water mist nozzle connected to the water passage cavity groove is provided at the center of the lower end face of the water mist nozzle.
[0012] Compared with the prior art, the fine water mist nozzle provided by this utility model has at least the following beneficial effects:
[0013] The positioning and sealing mechanism applies pressure to the sealing gasket at the end of the connected water supply pipe to achieve a seal and prevent leakage. The positioning and reinforcement pipe also plays a guiding role in the installation of the water supply pipe and reduces the possibility of misalignment.
[0014] By using the threaded collar and positioning reinforcement tube, the gasket can be easily disassembled and reassembled by removing the positioning reinforcement tube during the replacement process. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the inner wall of the water mist nozzle connector 1 is provided with an inner spiral pattern 10, and the side surface of the threaded collar 6 is provided with an outer spiral pattern 7.
[0023] Further as Figure 3 As shown, it is worth noting that the outer spiral thread 7 of the threaded collar 6 is threaded to match the inner spiral thread 10 of the water mist spray pipe connector 1, and a receiving gap 11 is provided between the positioning and reinforcing pipe 5 and the water mist spray pipe connector 1.
[0024] This solution has the following working process: Before use, the water supply pipe is sleeved on the positioning and reinforcing pipe 5 and tightened to the inner spiral thread 10 of the water mist spray pipe connector 1. The assembly sleeve 12 of the sealing gasket 8 is sleeved on the positioning and reinforcing pipe 5 and filled in the receiving gap 11. The end face of the water supply pipe connected in this way applies a pressing pressure to the sealing gasket 8 and achieves the function of sealing and preventing leakage. In addition, the positioning and reinforcing pipe 5 plays a positioning and guiding role in the installation of the water supply pipe and reduces the possibility of misalignment.

The assembly sleeve 12 of the sealing gasket 8 is adapted to the positioning and reinforcing tube 5. During the replacement of the sealing gasket 8, the positioning and reinforcing tube 5 of the water mist spray pipe connector 1 is rotated, which drives the threaded collar 6 to rotate out along the inner spiral pattern 10 of the water mist spray pipe connector 1 through the outer spiral pattern 7. In this way, the sealing gasket 8 can be lifted during the removal of the positioning and reinforcing tube 5, thus achieving the effect of easy disassembly and assembly.
[0027] Further as Figure 4 As shown, it is worth noting that the sealing gasket 8 is placed between the water mist spray pipe joint 1 and the positioning and reinforcing pipe 5, and the positioning and reinforcing pipe 5 has a water inlet 9 inside.
[0028] Further as Figure 1 As shown, it is worth noting that the water mist nozzle connector 1 has a water passage groove 4 inside, the water inlet 9 of the positioning and reinforcing pipe 5 is connected to the water passage groove 4 of the water mist nozzle connector 1, and a fine water mist nozzle 3 connected to the water passage groove 4 is provided at the center of the lower end face of the water mist nozzle 2.
